Custom content ids and casting issues in Microservices

[Leinnan]

User is unable to cast to a custom item content.

Steps

• create a Beamable Unity project
• create a microservice
• in common library code shared between create a new item class:

using Beamable.Common.Content;  
using Beamable.Common.Inventory;  
  
[ContentType("newTestContent")]  
public class NewTestContent : ItemContent  
{  
}  
  
[System.Serializable]  
public class NewTestContentLink : ContentLink<NewTestContent>  
{  
}  
  
[System.Serializable]  
public class NewTestContentRef : NewTestContentRef<NewTestContent>  
{  
    public NewTestContentRef(string id) : base(id)  
    {  
    }  
  
    public NewTestContentRef()  
    {  
    }  
}  
  
[System.Serializable]  
public class NewTestContentRef<TContent> : ContentRef<TContent> where TContent : NewTestContent, new()  
{  
    public NewTestContentRef(string id) : base(id)  
    {  
    }  
  
    public NewTestContentRef()  
    {  
    }  
}

• Create a new content of NewTestContent type in Content Manager and publish it: items.newTestContent.myTestContent
• Add this method to the microservice:

[ClientCallable]  
public async Task Test1()  
{  
    try  
    {  
        InventoryUpdateBuilder iub = new InventoryUpdateBuilder();  
        iub.AddItem("items.newTestContent.myTestContent", new Dictionary<string, string>());  
  
        await Services.Inventory.Update(iub);  
        var items = await Services.Inventory.GetItems( new ItemRef("items.newTestContent.myTestContent"));  
        for(int i = 0; i < items.Count; i++)  
        {  
            ItemContent itemContent = items[i].ItemContent;  
            BeamableLogger.Log($"Type: {itemContent.ContentType}, Id: {itemContent.Id}, Name: {itemContent.ContentName}");  
            NewTestContent concreteItem = itemContent as NewTestContent; // As resolves to null instead of NewTestContent  
            if(concreteItem == null)  
            {  
                BeamableLogger.LogError("The item is null");  
            }  
        }  
    }  
    catch (Exception e)  
    {  
        BeamableLogger.LogException(e);  
    }  
}

• Call the microservice endpoint from newly created BeamContext in the Unity.

Expected result

• Microservice outputs something like: Type: items.newTestContent, Id: items.newTestContent.myTestContent, Name: myTestContent
• concreteItem is not null

Current result

• Microservice outputs: Type: items, Id: items.myTestContent, Name: myTestContent
• concreteItem is null
